Application filed October 13, 1920. Serial No. 416,712.

To all whom t may concern Be it known that I, DMYTRO CYGANCZUK, a subject of the King of Great Britain, and a resident of the city of Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Pulverizers, of which the following is the specification.

The invention relates to improvementsin pulverizers and the object of the invention is to provide a pulverizer in the form of a roller which can be drawn over the field and will effectively pulverize the soil.

A further object is to construct the roller of the pulverizer from a number of similar sections which can be readily assembled and which are individually formed from sheet metal plates toothed at their edges and bent to present nonopposed rows of teeth.

lVith the above more important objects in View, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described, reference being had to the accompanying drawing in which Fig. 1 is a plan view of the complete pulverizer, part being broken away to expose construction.

Fig. 2 is an end view of the toothed roller.

Fig. 3 is a. side view of one end of the roller,

Fig. 4 is a perspective view of a. portion of one of the sections.

In the drawing like characters of reference indicate corresponding parts in the several figurese In these drawings l designates a substantially rectangular frame provided at the ends with end bearings 2 and fitted centrally at the front with an extending tongue 3.

The bearings carry rotatably the end spindles 4; and 5 of a toothed roller 6, the roller being constructed in detail as now described.

The present roller is formed from four similar sections, the sections being identically constructed and each being made from a comparatively heavy sheet metal plate having the opposite edges cut or notched in a V-shaped manner to provide rows of teeth 7 and 8. After the plate is so cut it is bent centrally of its length into a U-shape and bolt openings 9 andy 10 are made in the plate for fastening purposes.

The end spindles or stub-axles and. 5 are comparatively short and when one assembles the toothed roller he takes say four of the i toothed sections and groups them together as best shown in Figure Zwith the axles inserted between them and then bolts the sections together bycross bolts 11 provided. `When the bolts are tightened up the sections are all fastened permanently together and the inner ends of the spindles or axles are securely caught between the ends of the sections.

In forming the sections I prefer that the teeth be slightly staggered so that in the completed roller the teeth spiral around, such resulting in the more effective pulverizing of the ground on which the machine is operated. v

y From the above it will be seen that this toothed roller can' be very easily made, it simply being a matter of stamping out and bending the sections, cutting them olf to their proper length and then bolting them securely together after having inserted the end axles.

What I claim as my invention is 1. A `pulverizer in the form of a roller and comprising end axles and a plurality of similar toothed lengthwise extending sections, the sections being substantially U- shaped in cross section and grouped around the axles and fastened together by bolts.

2. A pulverizing roller comprising end axles and a plurality of similar substantially lol-shaped lengthwise extending sections grouped around the axles and secured together.

A pulverizing roller comprising end axles and a plurality of similar substantially U-shaped lengthwise exten-ding sections grouped around the axles and secured together, the said sections each having their edges toothed.

45. A pulverizing roller comprising end axles and a plurality of similar substantially U-shaped lengthwise extending sections grouped around the axles and secured together, the said sections each having their edges toothed and with the teeth staggered to spiral around the roller.
